The waters up in the Park have gotten bone skinny at this point in the fall, so size down your flies and tippet to some 6x and #18s to #22s in most situations. Little caddis, ants, beetles, and small hoppers are good bets on top. Favorite dries include stimulators, elk hair caddis, para adams, deer hair ants, para hoppers, and extended body PMDs. For nymphs, run beadhead BWOs, PMDs, midges, little dark stones, etc. in #16-18. Some of the lower high lakes can still fish well in early October, but this gets to be pretty hit-or-miss. Small zebra midges and other little nymphs like micro mays can be key in the fall in the Park. Watch out for spawning beds and be wary of where you step, as the brookies and browns will be looking to do their thing by this point in the season!

The Ultimate Fly Fishing Report
Casting a fly in a tranquil mountain stream, feeling the tug on the line, and holding a beautiful rainbow trout makes us feel alive and intensely connected with nature. Fly fishing is our way of life and we are blessed with hundreds of nearby rivers and streams just a short distance away from Boulder. From the swift spring waters of the Clear Creek to the meandering bends of the South Platte, it's critical to consider fishing conditions in advance and prepare accordingly. We rely on our experienced guides who venture into the wild to let us know which rivers favor fly fishing, where fish are biting, and which fly patterns are most effective. Planning a successful fishing trip also requires knowledge of stream flows at various river points and an accurate weather forecast for a given destination. At Rocky Mountain Anglers, we are dedicated to providing all avid anglers with detailed and timely information about hatches, water, and weather conditions. So before you head out the door on your next fishing adventure, visit our web site to find valuable information that will prepare you for a successful trip. Have fun chasing after your next trophy trout and enjoy nature's beauty!The Rocky Mountain Anglers Crew
